Do this: immediately after dinner, literally within few minutes (important), go for a 15 minute walk. Just go into any direction away from home for 8 minutes and you'll be forced to return for same amount of time—that's your anchor which will turn into structure. Doing this promotes faster stomach emptying and forces some glucose into muscles rather than all to fat storage. Over time, you'll want to go longer and structure less important horseshit around it.
You can elevate these benefits by doing pushups and squats 30 mins before the meal. Just one or two (2-3 minutes apart) sets is enough—don't even count the reps. Do as many as you can in each set.
