Can I Take Diet Pills While Intermittent Fasting?

Intermittent fasting is a modern trend with many health benefits. However, diet pills can be dangerous when combined with this type of fast. It’s important to know how these supplements interact before you start intermittent fasting or use them while on the program

The “does taking pills break intermittent fasting” is a question that has been asked by many people. The answer to the question is yes, but you should take diet pills with caution.

Can I Take Diet Pills While Intermittent Fasting?

With an efficient, fasting-friendly fat burner stack, you may improve your intermittent fasting outcomes.

The most tempting part of the intermittent fasting diet is that it isn’t truly a diet in the usual meaning of the word.

The focus of intermittent fasting is on when you eat rather than what you consume.

Intermittent fasting, as the name implies, is refraining from eating for certain periods of time to enable the body to re-calibrate its metabolism via fasting-related bio-pathways.

Intermittent fasting, as a weight-loss approach, fundamentally promotes the body to utilise stored fat as a source of energy instead of food. [1]

After all, why would your body need to activate its fat-burning systems if you’re continuously eating? It has an endless supply of energy thanks to all the food you’re continuously stuffing in its face!

Does this, however, imply you must abstain from all foods and substances, including fat burners?

Is it possible to use diet tablets when intermittent fasting, or do they break the fast? It depends entirely on the supplements you’re taking.

Fortunately, in this post, we’ll go over not just one of the greatest fat burner supplements for maximizing your exercise-related fat burns, but also one of the best diet pill stacks for avoiding breaking your fast when intermittent fasting.

Here’s a brief rundown of the finest intermittent fasting diet pill formula:

What is Intermittent Fasting (IF) exactly?

The majority of weight-loss or “dieting” solutions include limiting or eliminating particular items from your diet. This is why it’s a running joke that you can’t spell “dieting” without the word “death”… or at least that was the joke until it got too cliché to stomach.

Diets that compel you to severely reduce your calorie consumption or exclude particular macronutrients entirely are not exactly good for you, as the joke implies.

Today’s health and fitness programs, on the other hand, take a more sophisticated approach to improving…well, your health and fitness. Intermittent fasting is one such subtle approach: [4]

  • Intermittent fasting (IF) is a kind of eating that alternates between feeding (eating) and fasting intervals (not eating). In contrast to standard diets, intermittent fasting focuses on when rather than what you should consume.

As a result, intermittent fasting does not need restricting overall calorie intake; rather, it necessitates restricting total caloric intake to a predetermined “feeding” window.

Although you should aim for entire foods and nutritional richness in your diet, anybody may practice intermittent fasting, regardless of their diet or calorie intake. However, as with the adoption of any important health practice, one of the (many) benefits of intermittent fasting is how it indirectly affects many other elements of your health and fitness.

Intermittent Fasting: Frequently Asked Questions

Intermittent Fasting or Caloric Restriction: Which Is Better?

Intermittent fasting is possible without calorie restriction, and caloric restriction is possible without intermittent fasting. You may also practice both, of course.

However, since caloric restriction (i.e., eating less) is a natural result of intermittent fasting, and because you’re more likely to eat less when you’re not eating all day, it’s best to focus your diet on intermittent fasting rather than calorie restriction.

Intermittent Fasting + Energy Balance is the Next Step

Even better than calorie restriction, you should concentrate on energy balance (matching your caloric intake with your caloric expenditure) rather than merely calorie reduction. Here are some of the reasons why:

  1. Calorie restriction is also nutritional restriction: consuming fewer calories reduces your intake of key elements such vitamins, minerals, amino acids, and other nutrients, which may lead to malnutrition. [5]
  2. Increasing your energy expenditure (through exercise) to match your energy intake (through food) is not only more long-term sustainable, but also healthier in terms of athletic fitness, muscular strength, and vitality. [6]

Seeking energy balance by increasing your exercise activity, when combined with intermittent fasting, may dramatically enhance your metabolic performance and body composition, particularly when compared to strict calorie restriction. One of the secrets to gaining muscle while losing fat is to do so.

Is the Keto Diet Related to Intermittent Fasting?

Many people wonder about this because of the link between intermittent fasting and ketogenesis. You may be wondering what ketogenesis is.

  • Ketogenesis is a metabolic process in which fatty acids and ketogenic amino acids are broken down into ketone bodies, which are used as an energy source during fasting or calorie restriction. [7]

In the absence of nutritional energy fuel, such as glucose, the body switches to ketogenesis, or the utilization of stored fat for energy. Unlike the keto diet, which promotes ketogenesis by consuming a high-fat, high-protein, low-carbohydrate diet, intermittent fasting promotes ketogenesis by avoiding eating for a period of time.

Naturally, the two work hand in hand, but you don’t have to follow the keto diet to practice intermittent fasting. However, intermittent fasting may help you get better keto diet outcomes.

What exactly is rushed training?

Fasted exercise is simply exercising on an empty stomach as part of an intermittent fasting plan to increase calorie burn and accelerate fat reduction. Fasted exercise, which is best done first thing in the morning, pushes the body to burn fat for energy, resulting in a “well-fed” body that promotes appetite control and reduces overeating throughout the day.

  • Researchers found that “fasting before morning exercise lowered 24-hour energy intake and boosted fat oxidation during exercise” in a 2016 study on the impact of fasting before morning exercise on 24-hour energy intake (eating).

Is Working Out on an Empty Stomach Safe?

Yes, for the most part.

Exercising on an empty stomach is safe as long as you eat enough (and healthily enough) during the feeding periods of your intermittent fasting routine.

However, not only in terms of the 24-hour daily cycle, but also in terms of your fast-feed schedule, the safety and efficacy of your fasted training is primarily determined by when you choose to exercise.

What is the Most Effective Intermittent Fasting Routine?

Following is the best intermittent fasting Plus fasted training schedule:

  • Morning Exercise — to promote enhanced fat oxidation and reduced 24-hour energy intake (i.e., overeating) throughout the day. [9]
  • Early-Morning Eating — Participants who reported eating more calories in the morning than in the evening lost more weight in two weight-loss treatments. [10]

With that in mind, a variety of intermittent fasting plans are available, ranging from daily 14-16 hour fasts to weekly 24-48 hour fasts. Obviously, your optimum timetable is very dependent on your own calendar—for example, your employment hours, family obligations, and so on.

Despite this, studies shows that exercising and eating first thing in the morning is ideal for fat reduction and appetite control. So, if you’re planning a 14-16 hour daily fast, work out first thing in the morning and start your daily meal with a post-workout breakfast, with the fast beginning in the evening.

Is it possible to take supplements when fasting?

Returning to the original issue, can I use diet pills during intermittent fasting? In general, you may take various vitamins while fasting.

Of course, macronutrient supplements like protein powders and intra-workout carbs aren’t allowed to be used while fasting, but they’re OK afterward. In fact, a post-workout protein smoothie may be preferable than breaking your fast.

Many nootropic supplements, caffeine pills, diet pills, fat burners, and even, to a degree, BCAA stacks, include micronutrient-based compositions that may help you boost your health and performance without breaking your fast. Although we’ll be concentrating on the IF benefits of using a fat burner pill in this post.

Taking a Fat Burner While Intermittent Fasting Has Its Benefits


Including a potent fat burner in your daily supplement regimen may go a long way toward achieving a healthy metabolic energy balance. Fat burners, especially when taken before exercise, may assist maximize the benefits of fasted training while avoiding the drawbacks, such as muscular catabolism caused by fasting (breakdown). [11]

Using a fat burner during intermittent fasting, particularly when combined with fasted exercise, may help you achieve your fitness goals by:

  • Pre-Workout Thermogenesis Boost
  • Hard-working muscle tissue is protected.
  • Increasing Muscle Stamina and Exercise Endurance
  • Blood Sugar Control and Fat Storage Limitation
  • Controlling Your Appetite and Cravings

Overall, an efficient pre-workout fat burner stack may assist enhance fat burning while shielding against the muscular catabolizing effects of fasting. As a consequence, you’ll lose more fat and acquire more muscle mass in less time.

Will Diet Pills Keep Me From Entering Ketosis?

One of the most common worries about taking supplements while fasting is if they may knock you out of ketosis.

This varies every supplement, but the answer is typically no for all of the “micronutrient” supplements mentioned. In fact, certain supplements, like MCT (medium-chain triglyceride) oil, may work in tandem with intermittent fasting to boost ketogenesis even more.

Find out more about the most effective MCT oil supplement.

Which Ingredients to Look for in an Intermittent Fasting Diet Pill

Though there are a variety of fat burner supplements available, the most of them are just pricey, overdosed caffeine tablets. When coffee has thermogenic benefits, the following are the finest stim-free fat burners to ingest while intermittent fasting:

1) -Hydroxy-Methylbutyrate (HMB)

HMB is a bioactive metabolite of L-leucine, the most anabolic BCAA, and is one of the most effective fat burner supplements you can take when exercising on an empty stomach or following a calorie-restricted diet. This is due in part to HMB’s ability to protect muscles against catabolism (breakdown) during exercise.

HMB promotes lean muscle development and fat reduction by:[12,13]

  • Fasting-related protein-damaging enzymes must be neutralized.
  • To improve performance, increase oxygen intake.
  • Within the mTOR pathway, promoting protein synthesis
  • During calorie restriction, encouraging the use of stored fat as a source of energy

HMB is the ultimate fat burner for sculpting a lean, mean, athletic body since it protects muscle tissue while while encouraging fat burning.

One research from 2017 looked at the effects of HMB supplementation on physical ability, body composition, and many biochemical parameters in combat sports participants, and found that:

“Providing HMB to combat sports athletes causes beneficial changes in body composition and induces an improvement in aerobic and anaerobic capability.” [14]

2) Extract of Coleus Forskohlii (Forskolin)

Coleus forskohlii is the sole natural source of forskolin, a labdane diterpene linked to fat reduction. It’s a unique fat burner appreciated by bodybuilders since forskolin seems to function via:[15]

  • Thyroid and testosterone activities, as well as metabolism, thermogenesis, and anabolic muscle development, are all regulated by hormonal cell messengers.
  • Activating the protein kinase enzyme, which causes lipolysis, or the breakdown of triglycerides, the building blocks of stored body fat.

Forskolin triggers a cascade of metabolic bio-effects related with thermogenic fat reduction and anabolic muscle building by boosting cAMP activity.

One research from 2015 revealed that 250 mg of Coleus forskohlii extract, compared to placebo, was an effective weight reduction aid when used in combination with a hypocaloric (low-calorie) diet. The results of the research indicated that:

“In combination with a hypocaloric diet, C. forskohlii extract may be effective in the control of metabolic risk factors.” [16]

Forslean® is the best Coleus Forskohlii for intermittent fasting.

Forslean®, which is standardized to a powerful 10% forskolin, is the greatest Coleus forskohlii extract for intermittent use—and the best Coleus forskohlii extract overall. When paired with fasted exercise, Forslean® is a potent bodybuilding tool for pushing body composition away from storing fat and toward growing lean muscle.

3) Extract of cayenne pepper (Capsaicinoids)

Cayenne Pepper is a sort of popular chili pepper that is widely used to spice food. Its intense increase of thermogenesis actually burns fat. Cayenne pepper, which contains bioactive capsaicinoids, a type of “irritating” chemicals known for chilies’ spiciness, aids fat loss by releasing non-stimulatory catecholamines such as adrenaline and norepinephrine.

These catecholamines, in turn, enhance thermogenesis by:[17,18]

  • Stimulating beta-adrenergic receptors, which improve energy expenditure and calorie burn during exercise.
  • Hormone-sensitive lipase is activated, which catalyzes lipolysis or fat breakdown and improves fat mobilization and oxidation during and after exercise.

Capsaicinoids, namely capsaicin, provide metabolic advantages without the normal stimulatory effects of pre-catecholamine fat burning.

Capsimax®, a strong cayenne pepper extract brand (see below), was studied in 2010 for its effects on catecholamine production and blood indicators of lipolysis, with data indicating that:

“As compared to placebo, low dosage (2 mg) CapsimaxTM was linked with an increase in blood FFA [free fatty acids] and glycerol at specified intervals after intake,” with no effects on “HR [heart rate], SBP [systolic], or DBP [diastolic blood pressure,” [19]

As a result, the usage of cayenne pepper extract as a safe stim-free fat burner is supported.

Capsimax® is the best cayenne pepper extract for intermittent fasting.

Capsimax® is a revolutionary cayenne pepper extract brand that combines OmniBeadTM microsphere “beadlet” technology to assist prevent the stomach burning impact associated with hot peppers while still maintaining the extract’s fiery-hot fat-burning properties.

4) Chromium GTF

GTF Chromium (Glucose Tolerance Factor Chromium) is a complex of compounds linked with whole food sources, most notably brewer’s yeast, in addition to the trace element chromium. GTF chromium works as a fat-burning substance by:

  • Insulin activity and fat storage optimization
  • Macronutrient metabolism support
  • Controlling hunger and blood sugar levels

Because of its well-documented effects on nutrition metabolism and appetite regulation, GTF Chromium is highly appreciated as a promoter of lean body composition.

There is plenty of evidence to back up the use of chromium supplementation for fat loss, including two human and animal studies that showed chromium to have “a function in food intake management, which may be mediated by a direct action on the brain.” [20]       

NutriGenesis® is the best GTF Chromium for Intermittent Fasting.

NutriGenesis® GTF Chromium is a lab-created, nature-identical mineral form that has been neatly complexed with natural cofactors including probiotics, fibers, enzymes, and antioxidants to improve bioavailability and bio-efficacy.

5) Extract of black pepper (Piperine)

Black Pepper Extract is often added to supplements to improve nutrient absorption, but it also works as a fat burner because to piperine, a bioactive ingredient of black pepper.

Piperine has a two-pronged strategy to help people lose weight:

  1. Enhances energy expenditure via stimulating thermogenesis.
  2. Adipogenesis, or the production of new fat cells, is inhibited.

Piperine stimulates energy expenditure (calorie burning) while also preventing dietary fuel from being converted to stored fat.

Black pepper extract makes sense in many supplements since it may greatly boost component absorption and consequently bioavailability when used in small doses. Black pepper extract, on the other hand, is required in fat burners.

BioPerine® is the best black pepper extract for intermittent fasting.

BioPerine®, the go-to black pepper extract component, provides a highly concentrated piperine extract with a 95 percent standardization. BioPerine® is far more strong and efficient in aiding digestion and curbing major fat buildup than raw black pepper, which only contains 3-9 percent piperine.
