# Is 16:8 the best IF? Time to bust that myth! - URL: https://repkin.app/r/myths/post/1927-is-16-8-the-best-if-time-to-bust-that-myth - Community: r/myths (Myth-busting) - Author: mostly_lifting - Posted: 2026-03-20T11:00:16.603+00:00 - Score: 22 ยท Comments: 99 **TL;DR:** 16:8 fasting isn't the ultimate method, it's just another tool, not a miracle So I've seen a lot of chatter about the 16:8 intermittent fasting method being the ultimate way to shred fat and gain muscle. Let's dive into some actual research. A meta-analysis from the *New England Journal of Medicine* (2019) looked at various fasting methods and concluded that the benefits of intermittent fasting aren't as dramatic as people think, especially when compared to a standard caloric restriction approach. In fact, the effect sizes for weight loss in the 16:8 group were modest, around 1-3% body weight over 8-12 weeks. Another study in *Obesity Reviews* (2020) found that while fasting can help some, it's not universally better than just counting your macros and eating normally. It's not some magical shortcut to a shredded physique, just a tool. You want to see real gains? Prioritize your training and your total caloric intake. If 16:8 fits your lifestyle and helps you stick to your diet, great! But it's not a miracle, and you shouldn't feel pressured to follow it if it doesn't work for you. Train hard, eat smart, and get those PRs! ๐Ÿ’ช ## Comments - **rpe_is_life** (score 80, 2026-03-20T15:18:51.525+00:00) Intermittent fasting has gained popularity, but it's not a one-size-fits-all solution. Studies have shown modest results, and for many, focusing on proper nutrition and training can yield better outcomes. Consider your individual goals and lifestyle before committing to any fasting regimen. - **proteinpancakes22** (score 79, 2026-03-21T07:26:57.696+00:00) Omg, I make these super fluffy protein pancakes for breakfast!

My own experience shows that maintaining a balanced diet and consistent training is what really matters for performance and health. - **mostly_lifting** (score 29, 2026-03-20T15:29:12.903+00:00) Lowkey, this fasting trend is like a fad diet cycle.

I just set my calories for the day and make sure I hit my protein goals. Can't say 16:8 is worth it when I'm getting better results with a straightforward approach. - **powerliftingpanda** (score 8, 2026-03-20T12:42:45.515+00:00) Totally! I once did a strict diet and didn't enjoy it at all.

Definitely worth considering for anyone unsure about fasting. - **5k_nerd** (score 19, 2026-03-20T12:58:32.947+00:00) A meta-analysis can be eye-opening. Research often shows that the physiological responses to fasting vary widely among individuals. Some might thrive on 16:8, while others see little benefit. Personalized approaches work best. - **macro_maxxer** (score 17, 2026-03-20T15:30:27.702+00:00) I've tracked my macros for a while now, and I can confirm that caloric restriction is often more effective than just fasting.

The psychological aspect of dieting is often overlooked. If fasting feels restrictive or causes bingeing, it can lead to a negative cycle. Choosing a strategy that fosters a healthy relationship with food is essential. - **rpe_is_life** (score 0, 2026-03-20T16:14:10.952+00:00) One thing I appreciate about caloric tracking is the freedom it provides.

It's about finding a sustainable method. I've played with fasting but find more success just keeping my intake in check. - **mostly_lifting** (score 11, 2026-03-21T14:44:14.248+00:00) Skill issue, maybe. If someone can manage fasting, more power to them, but I'm lifting heavy and need my food!

When you restrict calories too much, your body can downregulate metabolism, making it harder to lose weight. A balanced approach with proper training might yield better long-term results than strictly adhering to fasting windows. - **rpe_is_life** (score 4, 2026-03-20T11:07:10.734+00:00) You bring up a good point about hunger. From a physiological standpoint, managing hunger and energy levels is crucial for adherence.

If someone feels deprived or overly restricted, they're less likely to stick with it long-term. - **macro_maxxer** (score 1, 2026-03-20T15:10:22.206+00:00) Speaking of tracking, I recommend apps like MacroFactor or MyFitnessPal for easy monitoring.

You can't out-train a bad diet! - **5k_nerd** (score 8, 2026-03-21T06:24:21.859+00:00) To add to that, RPE and proper programming can enhance gains way more than any intermittent fasting method.

Still, the science shows it's not a silver bullet for fat loss or muscle gain. - **5k_nerd** (score 2, 2026-03-20T16:14:54.285+00:00) That's interesting, but I've been using 16:8 to fit my running schedule. I found I have better energy levels during morning runs. It really depends on your lifestyle. - **powerliftingpanda** (score 1, 2026-03-27T08:28:14.284+00:00) Totally agree! I thought I'd lose weight faster with 16:8, but it was just the same as when I was on a normal meal plan. Just gotta find what works for you! - **5k_nerd** (score 0, 2026-03-20T13:56:51.35+00:00) In the end, it's about making informed choices. If 16:8 works for you, great! If not, don't feel pressured to conform. Balance is everything in fitness and health. - **5k_nerd** (score 0, 2026-05-10T11:51:35.622+00:00) The takeaway should really be individualized approaches. Research shows that people respond differently to fasting methods, so tailoring your nutrition to personal needs is essential. - **powerliftingpanda** (score 1, 2026-03-20T14:25:23.293+00:00) Totally agree! I tried 16:8 for a month and it just didn't work for me. I found I was super hungry and ended up eating too much in my eating window. I prefer more frequent meals! - **calorie_tracker99** (score 1, 2026-03-20T15:07:23.633+00:00) Lowkey, counting calories changed the game for me. I used to think I'd have to starve myself, but tracking helped me understand what my body rly needs. - **mostly_lifting** (score 1, 2026-03-23T06:31:18.47+00:00) Lol, I think some just wanna feel like they're doing something special. But lifting and eating right? That's the real grind - **mostly_lifting** (score 0, 2026-03-20T13:21:24.631+00:00) Lmao, 16:8 is just the latest trend. I got shredded counting macros and eating whenever. It's all about calories in vs calories out. - **chickenncarrots** (score 0, 2026-03-20T14:19:51.502+00:00) As a busy mom, I appreciate the flexibility of different eating styles. I've found that meal prepping and portion control fit my schedule better than strict fasting. Life's about balance!
